Dental Diamond Burs

The dental practice utilizes various dental instruments. Each instrument has its own set of characteristics and functions. Hand instruments and rotary instruments are two main classes of dental instruments. The rotary instruments are high-speed instruments that have excellent cutting and abrasive abilities. Dental burs are the main rotary instruments widely used in dentistry.

Dental burs are; rotary instruments that have cutting abilities and bladed heads used for tooth grinding and cutting purposes. Usually, the dental burs are made of carbide and diamond. Both have efficient cutting ability and strength.

Our proprietary multilevel diamond application results in uniform crystal coverage, which enables faster, smoother and more comfortable cutting. In addition, we use only natural diamonds for our gold diamond dental burs, because they offer superior cutting efficiency and long instrument life.

Diamond burs or rotary burs are divided into three main segments.

Burs’ head, burs shaft and shank.

• Shank

Shank is the part of diamond burs that makes the connection with the handpiece. the different shank design used in dental burs and each has its specific functions. The most common shank designs are;

• Long shank

A long shank of diamond burs is compatible with the straight handpiece. The handpiece for the long shank design is a slow speed rotary handpiece.

• Short Shank

The design is used for the contra-angle slow speed handpiece. It is also called Latch type design.

• Friction Grip

The most widely used diamond burs used in dentistry shank design is also denoted as FG shank design. In diamond burs, the FG shank is suitable for high-speed handpieces.

Dental burs are essential for the cutting and grinding of the tooth during the restoration and crown preparation. Few factors play an important role in the effectiveness of dental burs.

Dental diamond burs best prices

1.Size of burs abrasive particles:
The smaller size of abrasive particles offers more efficient cutting. The tooth penetration ability is higher for the finer particles they also provide rapid cutting and saves time and effort during dental procedures.

2.Shapes of bur particles:

The irregular particles are more efficient for cutting and grinding. The round particles are usually slow at speed and take more time for cutting.

3.Hardness of particles:

The hardness of particles related to the cutting ability. The harder the abrasive more efficient and excellent cutting ability of bur.

4.Density of Particles

Density is the number of abrasive particles per unit area. The closely packed particles are denser than widely spaced abrasive particles.

5. speed and pressure on dental burs.

The high-speed handpieces are responsible for fast and rapid cutting. The burst pressure and speed are related to each other. High pressure without high speed can lead to burst failure. Similarly, high speed can cause accidental damage to the tooth and oral tissue. Heat production and pulp damage are common at high speed.

6. Clogging of particles.

The debris during the cutting can clog the abrasive dental burs. The clogging reduces the efficacy and cutting ability. The compacted particles have more clogging than widely spaced. The use of constant water spray during the cutting can reduce the clogging and increases the working life of the bur.

CARE AND REUSE OF DIAMOND BURS:

For flawless cutting and longer shelf life, the care of dental burs is essential. The dentist should remove the burs after every procedure and clean them with cotton. The Diamond burs can be reused after sterilization. The most suitable sterilization procedure for Diamond burs is Autoclave or cleaning with 2% sodium nitrate solution.
